Motivated by these recent results, we explore the factors that determine U and we consider how these might scale to solar parameter regimes. To this end, we decrease the thermal diffusivity $\\kappa$ along two paths in parameter space. If the kinematic viscosity $\\nu$ is decreased proportionally with $\\kappa$ (fixing the Prandtl number $P_r = \\nu/\\kappa$), we find that U increases but asymptotes toward a constant value, as found by Featherstone & Hind","authors_text":"Bridget O'Mara, K.
